Color classpad announced

Helder7 was looking at international patents a while back and predicted a color classpad. Turns out, he was right!

The fx-CP400, comes which a large touch-panel color liquid crystal display (LCD) for easy viewing and operability with the incredible resolution of 320×528. We really need a screen upgrade, the old classpad screen quality was not the best.

This calculator will competing with the Nspire CX CAS.

The new Classpad model will be available in various countries starting in early summer 2013.

Casio just published the announcement on its Asia Website a few hours ago, but it seems that the other sites do not have an announcement up yet.

Helder made a table comparing it to other calcs, shown below.

Apparently will be more powerful than the prizm… kind of obvious, since the classpad has always been casio’s high-end calc.



flyingfisch’s 3d library

I made a simple 3d plotting library today.

Usage instructions and demo are included in archive.

Please post feedback on bugs and what functions should be added.


Happy Thanksgiving!

Also, Apple gets the flu on thanksgiving.

PRIZM Disassembly

1.) Take the back cover off. All the screws are the same so don’t worry.

2.) There are 2 screws connecting the boards to the front, as seen in photo below. Take them out and put them somewhere else (not with the regular screws).

3.) Turn the calc over and hold it by the edges. Now take a damp cotton swab and gently press down on each key until the key is below the front cover. Wipe around the inside of the hole. Now let the key raise back up and wipe the sides of the key. Do this with the rest of the keys.

4.) Put the 2 screws on the back into the boards.

5.) Put the back cover back on. hook it over the USB port and 3-pin port, and then guide the battery springs into their slots.

6.) Put all the screws back in.
